The World Anti-Doping Agency has confirmed it will not appeal against the United States Anti-Doping Agency's sanctions against Lance Armstrong.

Usada recommend that all Armstrong's results from 1 August 1998 be expunged, including his seven consecutive Tour de France wins from 1999 to 2005, and handed the 41-year-old a life ban from cycling.

The International Cycling Union last week ratified the sanctions imposed by Usada, which concluded Armstrong and his United States Postal Service team ran "the most sophisticated, professionalised and successful doping programme that sport has ever seen".

But whereas the UCI made some criticisms of Usada, Wada appears unequivocal in its support of the findings.

Commenting on the decision, its president, John Fahey, said: "Wada has no such concerns as to the complete process and the overwhelming weight of evidence. Rather it is of the opinion that the actions of Usada have highlighted the need in all cases for athletes to be able to come forward with evidence that will help rid sport of doping cheats."
